In the United States, headmasters and teachers discipline(惩戒) students in several ways. The teacher often writes or {#blank#}1{#/blank#} the student's parents. Sometimes students have to stay at {#blank#}2{#/blank#}for an extra hour. If a student behaves {#blank#}3{#/blank#}, the headmaster can suspend (勒令…休学) the student. The student cannot come to school for one, two, or three days, Sometimes, when the headmaster suspends some students, they are {#blank#}4{#/blank#}. "A three-day vacation!" they thought.

    Mr Lazares, a headmaster, didn't like to suspend students. When the boy who was not behaving well in class was sent to his {#blank#}5{#/blank#}, Mr Lazares telephoned the boy's parents. "If you come to school with your son, I won't {#blank#}6{#/blank#} him having classes," he said. The boy's father came to school and went with his son to every {#blank#}7{#/blank#}. Other students stared at the boy and his father. The boy was embarrassed. After that, he behaved better.  He didn't want his father to come to school {#blank#}8{#/blank#}. Other students behaved better, too. They thought, "I don't want my {#blank#}9{#/blank#}to come to school!"

    That year, about 60 parents came to school with children who didn't behave well. The next year, {#blank#}10{#/blank#}parents had to come to school. The students were behaving better.

Kim: Yes. The environment is very important to us. Everyone should do something for it.

Kim: Don't use {#blank#}4{#/blank#} bags.

Bob: But don't you think they are really convenient in our daily lives?

    Two brothers worked{#blank#}1{#/blank#}on the family farm. One was married and had a large family.{#blank#}2{#/blank#} was single. At the day's end, the brothers shared everything equally (平等地) .

    Then one day, the single brother said to{#blank#}3{#/blank#}, "It's not right that we should share equally the harvest. I'm alone and my needs are simple." So each night he took a bag of rice from his barn (仓库) and moved {#blank#}4{#/blank#}across the field between their houses, putting it into his{#blank#}5{#/blank#}barn.

    {#blank#}6{#/blank#}, the married brother said to himself, "It's not right that we should share everything equally. After all, I'm married and I have my wife and{#blank#}7{#/blank#} to look after me in years to come. My brother has no one to take care of him in future." So each night he took a bag of rice and put it into his single brother's barn.
